Patch for the patch

The attached patch seems to fix the problem.
GCC (C,C++) and CSiBE set compiles with it.  Now doing the full testsuite...

Kaz, if you have some time, could you try it out in your setup, too please?

A thing that bugs me regarding the attached patch is the big/little endian
subreg copy pasta in the patterns *negnegt, *movtt, *movt_qi.  Isn't there a
way to avoid that?
